spe - 11 - 8 - 0 5 1 / a 26 - july - 11 page 2 of 7 introduction the fxp810 has a peak gain of 1 .5 dbi at 2.4ghz and efficiencies of 60 - 7 0%, increasing to 5dbi and 80 - 90 % along bands 4.9ghz to 6ghz. at 31*31*0.1mm in size this antenna is uniquely valuable for small tag type mobile devices in that it can slip between the battery and the main pcb ground of small devices to get increased performance from the ground coupling effect. only the top 6.5mm radiating element needs to protrude out from the side of the main board, allowing such devices to have the highest possible performance at sm allest possible dimensions, it accomplishes this because it does not need clearance or footprint space on the device board itself that all on - board chip, loop and patch antennas need. i. specification electrical frequency 2.4 ~ 2.5ghz, 4.9 ~ 5.8ghz peak g ain (free space) 1.5dbi 5.1dbi peak gain (on plastic*) 2.4dbi 5.0dbi average gain (free space) - 2.6dbi - 1.1dbi average gain (on plastic) - 1.2dbi - 0.8dbi efficiency (free space) 56% 78% efficiency (on plastic) 76% 84% vswr Q 1.7 : 1 impedance 50 ohms polarization linear radiation pattern omni input power 2w max. mechanical dimensions 31mm * 31 mm *0.1mm antenna body material polymer cable gray 100mm 1.37 co - axial connector mmcx(m)ra environmental temperature range - 4 0c to 85c humidity non - condensing 65c 95% rh * on abs plastic 4mm
